Corrosion of second degree of chest wall, sequela

This code signifies a second-degree chemical burn affecting the chest wall, specifically documenting a late effect or complication of the initial injury. A second-degree corrosion involves damage to the epidermis and dermis, characterized by blistering, pain, and erythema, resulting from exposure to a corrosive substance. The "sequela" designation indicates that this code is used for conditions arising as a residual of the original corrosion, after the acute phase has passed.

Use this code when documenting a patient presenting with a long-term complication or residual condition directly attributable to a second-degree chemical burn of the chest wall that occurred in the past. Examples include persistent scarring, contractures, chronic pain, or other ongoing issues related to the original injury. This code is appropriate when the acute phase of the corrosion has resolved, and the current encounter addresses the lasting impact.

• Always sequence this code after the code for the specific sequela being treated (e.g., a code for scar formation or chronic pain).
• Ensure documentation clearly links the current condition to a previous second-degree chemical burn of the chest wall.
• The "S" in the 7th character indicates sequela; verify that the encounter is for a late effect and not an acute injury.
